Abstract The physical, optical, and structural-chemica l properties of the spicules of glass sponges Hyalonema sieboldi, Pheronema raphanus, Pheronema sp. and their cross-correlation and changes during the modification of the phase state of the spicule material are investigated. It is experimentally shown that the spicules of a sponge are nanocomposite three-dimensional periodic structures which consist of the organic matrix and the amorphous silica; the most characteristic feature of the biomaterials is a different degree of silicon hydration over the cross-section of spicules. The material of spicules has the spectral-selective characteristics of the transmission in the region of 190–1500-nm wavelengths, which is determined by their three-dimensional periodic structure, organic matrix, and amorphous hydrated silica, as well as by the functional special features of spicules. The data obtained make it possible to consider the spicules of sea glass sponges as a promising prototype for biomimetic simulation to produce nanostructured optical materials for systems and devices of photonics.
